# Example: Via CLI Uses RCM through the `rcm` command-line tool. ## Usage ```sh # Dry run — show what would change, make no changes rcm config.rb --dry # Verbose output rcm config.rb --debug # Limit execution to specific hosts rcm config.rb --hosts earth,mars # Apply configuration rcm config.rb ``` ## What it does - Creates `/tmp/example/hello.txt` with static content (parent directory created automatically) - Creates `/tmp/example/info.txt` from an inline ERB template containing the hostname and current date Both operations only run when the current hostname is `earth`.
